A Detroit gas station clerk is being charged with first-degree murder in the shooting death of a customer after an argument over the price of a box of condoms.

Kassim Saleh, 23, of Dearborn could face up to life in prison without parole if convicted of Saturday’s shooting death of 24-year-old Michael Haynes.

Wayne County Prosecutor Kym Worthy announced the charge, along with a felony firearm charge that carries a maximum punishment of mandatory two years in prison, at a news conference today.

“Any deliberation, no matter how short, in planning the crime can lead to first-degree premeditated murder,” Worthy said, adding that Haynes was unarmed and with friends as he tried to buy a box of condoms at about 1 a.m. Saturday.

According to investigators, Saleh was in a bullet-proof booth when Haynes questioned the high price of the condoms. After the argument, Haynes pushed over shelves of merchandise as he walked out.

Worthy said prosecutors have video evidence in the case.

“It is alleged that Mr. Saleh exited the enclosed room armed with a handgun and shot Haynes in the back as he was leaving the station,” Worthy said, adding that claims that Saleh shot into the ceiling to scare Haynes were untrue.

The shot hit Haynes in the shoulder and he later died at Sinai-Grace Hospital, according to Detroit Police.

Saleh, who has no criminal record, is scheduled to be arraigned at 1:30 p.m. today at 36th District Court.
